To ail iol-tom it may concern.

-Be it known that l, LAWRENCE G. Sinnen, c citizen or" the United States, residing at Cincinnati, in the county oi Hamilton and State of Uliio, have invented certain new and useful improvements in Scales; and .l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to new and useful improvements in scales and more particuiarly to a measuringapparatus therefor and the primary object is to provide a means for supplying materials to a scale and automatic means for cutting oii the supply thereof whereby only apredetermined amount may iiovv to the scale. A

further object of the invention .resides in providing an apparatus which may be applied to any scale now in use and a still :further object resides in providing a device which is simple and durable in construction,

f inexpensive to manufacture, and one which will be very efiicient and useful in operar tion.

tWith these and other objects in view, my invention consists in the novel eaturesof construction, combination and arrangement of arts as Will be hereinafter referred to an more particularly pointed'out in the specification and claims. I

in the accompanying drawings forming part of this application, Figure 1 is a front elevation of a'device constructed in accordance with my invention and set up for use;

Fig. is anend elevation thereof Fig. 3

is a verticalil transverse section of the device direction of the arrovv'; Fig. 4 is a similar View showing the cut-off in its lowered position; Fig. 5 is a horizontal section as seenon line t3-'5. of Fig. 4. In describing the' invention, I shall refer 'to the drawings in which similar characters beam 3 of which has'the pans 4 and 5 carried on theiends respectively thereof. The

form of scale shown is unimportant so far as this invention is concerned and any desired type of scale may be used in Which a pan is provided for the reception of the material or articles to be weighed. In the present instance, the pan 5 will` be desig noted as the pan for such purpose so that if desired, the other pan' may be entirely omitted.

My improved device contemplates the provision of means for supplying materialsto the scale pan and automatically cutting oil' said supply when the desired amount has ybeen passed to4 the scale. To this end, a frame 6 is provided which ismountcd for vertical adjustment upon the standards 7 carried at the ends of the pedestal 1. This frame is provided with a housing 8 a portion oi' which is designed to form a hopper Si., rthe latter having an outlet opening 10 which leads to a compartment 11 in said housing. The compartment 11 extends vertically of the housing and is open at its lower end, such termination beingr in vertical alinement with the scalepan 5 above relfererd to.' rilhus the materials contained in `the hopper Ei-may How-through the outlet opening 10 to a lower portion of the` compartment l1' of the housing downwardly to :the scale pan Lvvhich islarranged therebelow. Slidably mounted in the vertically arranged' Vcomparti'nent ll is a plunger or the like 12 which is designed to forma closure `for the outlet opening 10 of the hopper S), said l plunger only forming the closure, however, 'when the same is in its 4lowermost position in the compartment ll. l

il have provided an improved means for manually raising and automatically lower-L ing this'plunger and to this end, outwardly extending bearings 13 are provided on the iront of Ithe frame 6, the same having mounted for oscillation therein, an actuating shaft 14. Securely mounted vin additional outwardly extending bearings 15 above the' shaft 14, is an additional shaft 16, the latter beingr provided with a dependingarm or lug 17. .The lower end of this arm 1'7 is bifurcated and fiilcrumed between the 4furcations of this arm is an actuating leverzl. This lever is ulcrurned 'inter- Vmediate oi its ends' and the inner end t operable lever 23 secured thereto.

2 l incassa thereof has pivotal connection with an upstanding' lug 19 carried on the plunger 12, This lug 1*.) projects through a slot 90 in the iront 'all of the compartment 11 of the housing 8 and it will be seen 4from this construction that upon the downward pressure or pull upon the outer end of the lever 1S, an upward movement will be given the plunger to cause the same to be disposed to its raised and open position with respect to the outlet opening 10. 1

Secured on the shaft ,14 is a dish-like crank 21 which has pivoted thereto at a point adjacent its peripheraledge, one end of a rod or bar 22. The opposite end of this rod or bar has pivotal connection. with the outer end of the actuating lever 18. The one end of said shaft 14 has a manually Thus it will be seen that 'upon the actuation of said lever in one direction, the shaft M will be oscillated which, from the construction shown and above described, willcause said lever 1S to be swung on its tulcrum point to raise the plunger 19.

Loosely pivoted on the shaft 1G is an additional arm 24 which normally depends therefrom and is otfset intermediate of its ends to provide an arcuate lower portion rl`he outer edge of this arcuate portion 25 of.

the arm 2l is convexr and at the upper ternnnation of this couver; edge, or, in other Words, at the junction ot the distorted portion with the remaining;l portion ot the arm, a .notch or the like 2G is formed, the purpose of which will appear presently. Also carriel on the shalt ll to be actuated therewith, is an arm 27 the outer end of which has a. laterally extending; roller 28. 'lhis roller is disposed in such position as to engage the convex edge ot the arm *2l as the shaft llt is actuated lllhen the arm in such a position as to dispose the arcuate portion thereof downwardly with respect to the trame and the sha'lt is :nztuated so as to dispose the roller 2S upwardly on the convexY edge. ot said arni, said roller is adapted to be received in the notch 2G just referred to and assuming that the arm 2l will be vieldingly held in its extended position, said roller will be. held in this notch and thus retain the shal't lst and parts actuated thereby in their aetuatml positions, ln order to permit this portion olf the arm 2l tobe yieldine'ly supported iu its efitended position and actuated at predeterinined "times, an mljustable eonnectiiagr rod Q0 provided, the saine having connection at its one end with the lower or outer end ot the arin 2-1- and en aged at its` opposite end with the end oll the scale beam il adjacent which tho pan 5 is disposed.

ln the normal position ot! the device, that is, just prior to the supplying; orti-the materials to the scale pan, the. beam t) in' an unbalanced position, being so disposed by the application of a weight or weights thereto. 1n such position of the device, the plunger 12 is in its lowerm'ost position closing the outlet openingr 10 of the hopper and the arm 27 is in its lowered position with the roller 2S thereon engagedwvith the edge o'l said arm 24C adjacent its outer end. Assuming` that the scale has been propertly set to weigh a predetermined amount of material,

`the operatorflirst forces downwardly on the actuating lever 23 which causes the shaft 14 to be partially rotated in its bearings in the direction of the arrow shown in Fig. 2. lt will be understood that in the particular position shown and referred to ol' the scale beam, the connection between said beam and the outer end of the arm 24, will dispose the latter in an extended position with respect to the frame 6 and when the shalt lll is so actuated as just mentioned, the roller passing upwardly along the convex edge o the arcuate portion of said arm 2i will rest in the notch 26 of said arm. lt will also be understood that upon rthe actuation of the shaft 14, the plunger l2 will be raised to permit the contents ot the hopper 9 to flow through the outlet opening 10. The reception ot' the roller 2S in the notch 26 will cause the shaft 14- to be held in its actuated position soI that the plunger will be retained in its raised position thereby permitting the contents to llow steadily through thc-lower end of the compartment ll to the scale pan ll'hen an amount of material has been received on said pan sutlicient to over-balance the weights on theA scale,- it is obvious that this particular end of the scale beam will be forced downwardly thus drawingl dowriwartlly on the lower end ol the arm Q1 in view of the eminectinfr7 rod 29 and with such an actuation ot the arm Qt the notch will be drawn from the roller QS thus releasing the engagement tlnrelwtween and permitting' the arm QT to be lowered, which will 'cause the shall. Ill to be returned to its initial position. Such actuation obviously causes the plunger lil to be returned to its lowered and initir-l position thus closing; the outlet o'iening l0 and cutting.; ott the [tow of material troia the hoplier. lt will thus be seen that 'while this device is actuated manually in order to start the supply of material to the scale pan, the same actuates automatically to cut oli' said supply when a predetermined amounted is provided.

From the foregoing, it will be seen that l have provided a simple, inexpensive and' ellieient means for carrying` out the objects of the invention and while l haye particularly described the elements best adapted to pertorni the functions set forth, it is obvious that various changes in orin, proportion and in the minor detalls of construction may be resorted te Without departing Afrom the incassa.
